DS tells me Geography went well. Not 9 well, but well. he only knows of one marked that he definitely didn't get. However, all that means is that he's in a good place for the examiner to start deducting marks because "I know what you meant" does not cut it in Geography. (It has taken DS a while to come to terms with that!).
He said Biology went well. Again, only 1 mark he is certain that he didn't get.
If he does well in Biology, it will be a victory for Tassomai because he did a past paper over the Easter holidays and got it back 50 days ago today and he got somewhere around 60% (he was forecast a 9, soa bit of a drop). I signed him up to Tassomai that afternoon, and he's been using it ever since (that's how I know it was 50 days ago - the tassomai dashboard tells me).
With a lot of effort (8300 questions answered so far), he got up to 70-80% progress on each paper across all 3 sciences.
I'm writing all this down so that if someone googles Tassomai and reads these posts in future years, they'll be able to assess the effort versus outcome ratio when DS gets his results. He's hoping to get 8s in science, so we'll see what happens.
